<p>The object of the present invention is to provide a machine for blasting abrasives that has a simple structure and that solves the problem of abrasives falling when the door for the gateway for the work is opened or closed. The machine for blasting abrasives comprises a chamber 11 for processing, a nozzle 13 that is provided within the chamber 11 for shooting the abrasives (shots) S onto the work W, and a jig 15 for holding the work W at a position facing the nozzle 13. A gateway 17 with a door 19 is formed in the ceiling 11a of the chamber 11. The size of the gateway 17 enables the work W to protrude from the chamber 11 by means of the jig 15 at a position corresponding to the jig 15 that is linearly moving up and down. The door 19 is provided within the chamber 11 so as to seal the gateway by linearly moving up and down and so as to create a vacant plane on the gateway for passing the work by horizontally moving.</p> |
